My image won't render. Every time i go to render, all I got is a grey screen
Reason number 7 on this post:

OBJECTS ARE NOT WITHIN THE RANGE OF CAMERA CLIPPING

You have a scene with huge objects. Each of your figures is tall as a skyscraper.

The camera clipping distance is set to a short range that does not encompass your scene.



Increase the End clip distance.



But as a piece of unwanted advice: in Blender it is better to work in a scale that matches the real world. Physics, and other simulations, depth of field and lighting will behave differently depending on the scale.
